It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2022-48898 in the wild and no public exploit code.\n\nAffected product: Linux kernel. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-48898/ (Markdown: https://insights.sbomify.com/CVE-2022-48898/index.md)","id":"CVE-2022-48898","markdown":"https://insights.sbomify.com/CVE-2022-48898/index.md","name":"CVE-2022-48898","record":{"aliases":["DEBIAN-CVE-2022-48898","GHSA-p4ww-qww8-jc5f","UBUNTU-CVE-2022-48898"],"analysis":{"component_type":"kernel","fix_type":"patch","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Linux kernel driver","requires_auth":"low_privilege","summary":"A race condition in the Linux kernel DP driver causes premature completion of AUX transfers, leading to corrupted EDID data during boot.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Linux","cpe":[{"product":"linux_kernel","vendor":"linux"}],"cvss":{"score":4.7,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/msm/dp: do not complete dp_aux_cmd_fifo_tx() if irq is not for aux transfer\n\nThere are 3 possible interrupt sources are handled by DP controller,\nHPDstatus, Controller state changes and Aux read/write transaction.\nAt every irq, DP controller have to check isr status of every interrupt\nsources and service the interrupt if its isr status bits shows interrupts\nare pending. There is potential race condition may happen at current aux\nisr handler implementation since it is always complete dp_aux_cmd_fifo_tx()\neven irq is not for aux read or write transaction. This may cause aux read\ntransaction return premature if host aux data read is in the middle of\nwaiting for sink to complete transferring data to host while irq happen.\nThis will cause host's receiving buffer contains unexpected data.
